Re: Little red light on the front is a good way to lose energy
I'm pretty sure the red light you're talking about is the light sensor. The sensor activates when adaptive brightness is turned on in order to adjust your screen's brightness depending on the ambient light. That little red light turns on whenever your light sensor is working and don't quote me on this but I think the red light is necessary for your light sensor to function.
No worries, no one's spying on you if that light is turned on, it doesn't have much to do with the camera actually.
